Two similar cones have matching heights and radii whose lengths are in the ratio 6:5. Find the ratio of their surface areas.

Suppose the radius of a circle is 16. what issuppose the radius of a circle is 16. what is its circumference its circumference

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.

Y=21.95x+10 y=22.45x solve by substitution
